Abstract

1355694 Bushing insulators WESTING- HOUSE ELECTRIC CORP 6 Sept 1971 [28 Oct 1970] 41424/71 Heading H2C Longitudinal and radial grading of voltage distribution in an electrical bushing is undertaken by condenser systems 52, 54, 56; each system being preferably of the axially divided type. Serial connection between each system is provided by axially continuous layers of conductive material. A single layer may be used or as shown 76, 78 and 88, 90 a double layer electrically connected as at 79 or 92 which acts as a cooling duct. A cooling duct 82 may also be provided between the central conductor 60 and the first condenser system. Oil cooling is used.
